MACHINE FOR REGISTERING AT A DISTANCE ADMISSIONS BY TURNSTILES.

SPECIFICATION forming part of Letters Patent No. 735,279, dated August 4, 1903.

Application filed September 22,1902. Serial No. 124.462. (No model..

To whom; it may con-corn:

Be it known that i, ALBERT MARSH, a subject of the King of Great Britain, residing at 150 Oxford street, London, England, have invented new and useful Improvements in Means for Registering at a Distance All Admissions by Turnstiles and the Like, of which the following is a specification.

This invention relates to means for indiro eating at a distance the number of persons passing through a turnstile or the like.

According to my invention I provide means in connection with the turnstile for closingan eleciriccircuit by the rotation of theturn- 5 stile each time a person passes through the same, and I provide means at a distance from the turnstile for indicating the number of times the circuit is closed that is to say, the rqannrber of persons who have passed through 0, the turnstile.

In carrying out my invention I provide in operative connection with the spindle of the turnst-ile a series of contact-arms corresponding in number with the arms of the turnstile,

5 the said cont." "It-arms being designed to make contact with another contact or contacts in circuit with an electric battery or other elec- I tric generator, and I provide an electromagnet the armature of which serves to actuate a step by step a ratchet-wheel in connection with the train of wheels of a counting mechanism. The contact-arms are conveniently hinged to a spindle or to a hub on the spindie and provided with springs which make them of a yielding nature,and they make contact with double contact-pieces. One end of the said spindle engages one end of the turnstile-spindle, or it may be operated through the medium of gear-wheels from the turnstile-spindle. One or more of the gear-wheels of the counting mechanism I arrange movable on their arbors, so that they can be Withdrawn from gear with the other wheels'to enable the pointers to be readily set to zero. The counting mechanism I prefer to use is similar to that described in the specification ofomy United States Patent No. 693,414, of 19 2.

In the annexed drawings, Figure 1 is a sectional plan showing the table or upper part of a turnstile with the circuit-closing device counting mechanism.

4 is a sectional elevation of the counting mechanism, and Fig. 5 is a plan thereof. Fig.

6 is an elevation of a portion of the ease containing the counting mechanism.

a is the spindle of the turnstile, and Z) Z) bl) the arms thereof.

c is the table of the turnstile, and dis the box or recess, which the usual counting mechanism is arranged in connection with the spindle a and for which I substitute my contact-making device. e e e e are the spring contact-arms of the said device, corresponding in number with the arms b1) 1) b and mounted upon a spindle f, provided at its lower end with a key or projection f, which enters a slot 9 in the end of the spindle a, so as to be keyed to the said spindle.

h is the double contact, with which the arms 6 make contact as the arms I) are moved by the persons passing through the turnstile, one contact being made for each person. The contact-strips h are preferably of a spring nature, as shown.

The arms e are conveniently hinged to a hub e on the spindle f and have springs e behind them. By this construction they are rendered of a yielding nature, so that as they pass over the strips it this resilient character insures perfect contact and avoids unneepssary friction.

t is the battery or other electricity-generator, and j is the electromagnet, both of which are in circuit with the two contactstrips h by the wires 70.

Z is the armature of the at Z and provided with a pin Z designed to act against the inclined surfaces of the teeth of the ratchet-wheel wt to rotate the lattertooth by tooth.

j is a spring-detent engaging the wheel m and assisting to drive the same by its inclined end.

The ratchet-wheel m has ten teeth and isrnounted upon the arbor of the unit-wheel n and unit-pointer o of a train of wheels of a n n n indicate the said wheels in gear with one another. By

magnet j, pivoted this arrangement an electric-impulse produced by the contact of one of the arms 6 with the contact h will energize the magnet,

so as to attract its armature and actuate the ratchet-wheel to cause the pointer o to move through one division of its scale, and so indicate that one person has passed through the turnstile. i

The magnet j, armature Z, ratchet-wheel m, and train of wheelsn n n are similar to those described in my said former patent in connection with the recording mechanism therein.

In the drawings the counting mechanism is shown with three pointers 0 o o to indicate units, tens, and hundreds, respectively, and the wheels n on the arbor of the pointer 0' I arrange loose, but keyed upon the said arbor, so that by moving the said wheels longitudinally upon the arbor they can be moved out of gear with the wheels n M, whereby the pointers in connection with all the wheels can be readily set to zero, disks 1) being arranged upon the arbors to enable them to be turned.

q is a spring upon the arbor of the wheels n for returning the latter and holding them again in gear with the wheels 11 n 1 Instead of the arms a beingarranged to make contact with double contacts, as de-' scribed, it will be clear that they may be arranged to make contact with a single con tactpiece, the spindle of .the arms e being arranged in the electric circuit; also, instead of connecting the spindle f directly to the spindle a of the turnstile it may be arranged to be operated through the medium of gearwheels.

Having now described my invention, what described.

actuated by the magnet ,7, pin Z on the said I claim as new, and desire to secure by Letters 4 Patent, is-

1. The combination with a turnstil-e of a series of hinged spring contact-arms rotating around a center and positively operated by the rotation of the turnstile, double spring 4 contact-pieces with which the said arms make contact in their rotation, an electricity-generator and'an electrical register for recording the number of such contacts substantially as 2. The combination of theturnstile-spindle at, arms 12 connected thereto, spindle f keyed to the spindle a, hinged spring contact-arms e upon the spindlef, double spring-contacts h with which the arms e make contact, electricity-generator 11 in circuit with the contacts-h, electromaguetj in circuit with the generator 1; and the contacts h, armature Z armature, ratchet-wheel m actuated by the said pin, spring-detent j having an inclined end to assist in rotating the ratchet-wheel, train of gear-wheels n, n, n geared together, the wheels n being keyed to but movable longitudinally upon their arbor, pointers o, 0, Q2, disks p'upon the arbors of the said gear-wheels n, n, n aiid spring g on the arbor-of the gear-wheels n for returning the .7 said wheels into gear after being removed from gear with the wheels n, n? substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
